“He’s calling her his ‘little wife,’ which is cute but kind of odd since he’s not divorced yet,” a friend told Life & Style.

Even though Ashton, 34, only split from his wife, Demi Moore, last November, a source says “he is totally into Mila.”

While it’s obvious that Mila also has strong feelings for her former That ’70s Show co-star, she has no plans to rush to the alter. “Mila’s playing it cool with Ashton,” explained a friend. “She’s not pushing for a ring.”

And it seems the 29-year-old actress may never be pushing for one. “I’m not sure about marriage,” she recently revealed. “I see no need. I’ll be with somebody because I want to, not because a piece of paper tells me I have to.”

While their future as a couple remains unknown, the two seemed to be enjoying each other’s company at LA’s Casa Vega restaurant on Aug. 12. “They seemed completely relaxed and happy with each other,” reports an eyewitness. “They laughed a lot.”
